WINDING OR REWINDING MECHANISM FOR MECHANICAL MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent N 0. 683,717, dated October 1, 1901. Application filed Kay 13, 1901. Serial No. 60,068. (No model) To all when it may concern.-

Be it known that I, AURA E. WHITEHEAD, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Winding or Rewinding Mechanism for Mechanical Musical Instruments, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the construction of the driving mechanism for the take-up and paper roll of a self-playing musical instrument; and it consists particularly in the construction, arrangement, and combination of the various parts, as more fully hereinafter described.

In the drawings, Figure l is a vertical section through one end of the tracker-board box, showing the winding and rewinding device in elevation. Fig. 2 is an enlarged section illustrating the drive shaft and the clutch thereon. Fig. 3 is an elevationof the end of the tracker-board box, showing the device in elevation.

In the ordinary self-p1aying musical instrument the tracker-board, which is not shown, is ordinarily placed in a recess or box at the front of the machine. This box I re- Ier to as the tracker-board box, one end of it being shown as the vertical board A in the drawings, the other end, which is not shown, being a similar vertical board, in which two boards are journaled the ends of the supporting-shaft of the take-up roll B, and in which boards are supported suitable stubshafts, with which the ends of the paper-roll C may be detachably engaged.

D is the shaft of the take-up roll, which is journaled in the end boards of the trackerboard box, as shown in Fig. 1. On this shaft is a gear wheel E, which meshes with a pinion F on the drive-shaft G and which is constantly driven by any suitable motor (not shown) and which is journaled in a box or hearing II in the lower end of the shifting bar I. This shifting bar is supported in a groove or guideway J in the outer face of the end board A of the tracker-board box. It is provided with the slots at, through which project the screws b, which at once form holding means and a guide for the bar I. Upon the shaft G is a sprocketwheel K, with which engages a sprocket-chain K, which likewise en= gages a sprocket-pinion L on. the countershaft M. This counter-shaft is jonrnaled in the bracket N on the end board A. The inner end of the shaft M is provided with a socketed head 0 to receive the pin or lug on the paper-roll C. On the sprocket-pinion L is a grooved hub b, with which is engaged a yoke c on the end of the rock-arm d, which projects from a rock-shaft e, jonrnaled in the brackets 71, secured on the end board A, as plainly shown in Fig. 3. Depending from the rock-shaft eis an actuating rock-arm 'i, the lower end of which is connected by the link It with an actuatingdever l, which projects up through a slot in the bottom of the trackerboard box.

In the position of the parts shown in Fig. 1 the drive-shaft G will rotate the pinion F, which is in mesh with the gear-wheel E, and will drive the take-up roll B, thus feeding the perforated paper over the tracker-board for the purpose of causing the machine to play in the well-known manner. If it is desired to rewind the perforated strip upon the paper-roll C, the operator shifts the lever Z to the right, which through the connections described will rock the shaft 2 and the rockarm 0, sliding the sprocket-pinion L longitudinally upon its shaft M and causing a spur or pin m on the hub b to engage a corresponding spur or pin a on the collar 0, fixed to the shaft M, thereby rotating the shaft M and driving the paper-roll O, causing the perforated sheet to wind thereon.

In order to simultaneously disengage the pinion F from the gear-wheel E, I provide the rock-shaft 6 with a rock-arm 0, which engages a socket or recess '2- in the shifting bar I, which when the shaft 6 is rocked will press "down the shifting bar I and with it lower the shaft G into the position shown in dotted lines in Fig. 1, moving the pinion F away from and clear of the gear-wheel E. The sprocket-chain K is sufiiciently slack and swelling of the wood or even the racking struments, the combination of a tracker-board and the shaft G suificiently long to permit of this motion of the shaft to disengage the pinion from the gear-wheel.

Upon the shaft M, I arrange a brake-wheel Q, and I apply to this brake-wheel a springbrake R, having constant engagement therewith. This brake acts to slightly retard the rotation of the paper-r011 0, so as to put the necessary tension thereon between the rolls 0 and B in its passage over the tracker-board.

This device, as will be seen, is exceptionally simple in construction, positive in-operation, economical to build, and occupies but a very small space, the wh ole device being supported upon the end board A of the traeker-- board box, so that it will always be in proper fixed relation to the rolls B and O, which are journaled in that board. I Thus the shrinking of the instrument will not in any way affect the position or operation of the motor and its drive mechanism or materially increase the friction thereon, which of course would increase the power of the operator to drive the machine.

What I claim as my invention is- 1. In a self-playing device for musical inbox, the take-up roll journaled therein, the paper-roll, acounter-shaftin one'end'of which the paper-roll is detachably engaged, a driven shaft, a pinion thereon, a gear-wheel on the take-up roll, a drive connection from the driven shaft, a loose wheel on the countershaft, a clutch between the loose wheel and its shaft, a sliding bearing for the driven 1 l-ously actuating the clutch and the sliding bearing for the purpose described.

2. Ina winding and rewinding mechanism 40 for mechanical musical instruments, the combination of the rock-shaft e and an actuatinglever therefor, of the shifting bar I slidingly supported in bearings on the tracker-board box beside the rock-shaft, a driven shaft G journaled in said shifting bar and having a pinion adapted tobe engaged and disengaged with the gear-wheel on the take-up roll, of the rock-arm o engagingsaid shifting bar or rock arm a, a sprocket-pinion Z driven from the drive-shaft G, the counter-shaft M on which said sprocket-wheel is loosely 'journaled, a 1

grooved hub on the sprocket wheel with which the rock-arm c engagesand the clutch between the hub of the sprocket-pinion and the shaft M, substantially as and for the purpose described.

3. The combination with the tracker-board box of the take-up roll Bjonrnaled therein, of the end board A, the counter-shaft M jonr- 6o naled. on the end board, the drive-shaft 'G journaled thereon, the rock-shafts journaled in brackets supported on the end board and the winding and rewinding drive connections for the rolls B and O actuated from the rockshaft 6 substantially as described.

In testimony whereof Iaifix my signature in presence of two witnesses. AURA E. WHITEHEAD.
